Bis(μ-5-carboxylato-1-carboxylatomethyl-2-oxidopyridinium)-κ2O5:O1;κ2O1:O5-[diaqua(phenanthroline-κ2N,N′)manganese(II)] dihydrate

The centrosymmetric binuclear title complex, [Mn2(C8H5NO5)2(C12H8N2)2(H2O)4]·2H2O, was obtained by the reaction of manganese chloride with 5-carboxy-1-carboxymethyl-2-oxidopyridinium and 1,10-phenanthroline. The MnII atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxylato-1-carboxylatomethyl-2-oxidopyridinium ligands and two water molecules, leading to a distorted octahedral MnN2O4 environment. Intermolecular O—H...O hydrogen bonds link neighbouring molecules into a layer structure parallel to (001).
